range.intersectsNode

Summary

Obsoleto
Esta funcionalidad es obsoleta. Aunque puede aún funcionar en algunos navegadores, se desalienta su uso ya que puede ser removida en cualquier momento. Evite usarla.

Returns a boolean indicating whether the given node intersects the range.

Syntax

bool = range.intersectsNode( referenceNode )

Parameters

referenceNode 
The Node to compare with the Range.

Example

range = document.createRange();
range.selectNode(document.getElementsByTagName("div").item(0));
bool = range.intersectsNode(document.getElementsByTagName("p").item(0));

Notes

This method is obsolete; you should instead use the W3C DOM Range methods (see compareBoundaryPoints()).

Warning: This method has been removed from Gecko 1.9 and will not exist in future versions of Firefox; you should switch to compareBoundaryPoints() as soon as possible.

The following function can be used as replacement:

function rangeIntersectsNode(range, node) {
  var nodeRange = node.ownerDocument.createRange();
  try {
    nodeRange.selectNode(node);
  }
  catch (e) {
    nodeRange.selectNodeContents(node);
  }

  return range.compareBoundaryPoints(Range.END_TO_START, nodeRange) == -1 &&
         range.compareBoundaryPoints(Range.START_TO_END, nodeRange) == 1;
}

Specification

This method is not part of a specification.
